(Cl. 13534) This invention refers to umbrellas and particularly to arrangements for fastenin more of thread for securing the cloth in position on the stem, and use in place thereof, sive mechanical connection that does the satisfactorily fornormal usage.

It is an improvement of the arrangement described in the Patent Number 1,134,121 dated April 6, 19

become apparent as the The construction outlined in the patent referred to, provides for utilizing a screw threading function in addition to the press fit and look In the drawing which illustrates an example of a device exemplifying this invention:

Figure 1 is an elevation of a device embodying this invention partly in section;

Figure 2 is a side elevation of the outer ferrule, inner ferrule and rib-hinge-ring separated from each other and ready for assembly;

Figure 3 is a plan view of the rib-hinge ring;

Figure 4 is a side elevation of Figure 3;

away of a modified outer ferrule.

Similar reference characters parts throughout the drawing.

The construction outlined in the drawing shows the portion refer to similar tion selected for the sliding-up and mounting of a rib-hinge-ring 3. The latter is secured to ferrule 5 is pushed down to portion 6 of the rib-hinge-ring from over th end 2 and rests on the ring flange 21. This covering to catch and bind it between the ferrules. The outer ferrule has a screw-thread portion at rule NT OFF C 2 screw-threaded or helical form in the ferrules serves to bind the covering more firmly and divert the stress brought about, when the umbrella is opened and the covering stretched. The twist given to the cloth or material of the covering by the helical form of the ferrules serves to increase its resistance to removal from between the ferrules.

The rib-.hinge-ring ring flange 21 so as to provide a spacing between the rib-hinge portion l6 and the place of contact of the bottom edges of the ferrules on the upper face of the flange. its pivot l1 does not bring the rib into contact with the ferrules, because of this spacing. At the same time, the flat edge of the rib strikes the flat travel beyond the horizontal plane. of the covering also reinforces this action. This does not interfere with the ribs returning to their closed and vertical position when the umbrella is shut up. The outer ferrule isshown with its bottom l9 .closed-in-in: order to. eliminate the usual metal end piece provided.

While but two forms of the invention have been shown in the drawing and described in the specifications, it is not desired to limit :this application for patent to. such specific constructions or in any other way otherwise than limited-by the scope thereof, as it is appreciated-that other forms. of construction could be made that would use the same principles and: come within the scopeof theappended claims.

Having thus described the invention, whatxis" claimed is:

2. In combination with an umbrella stick of a covering fastenerv comprisinga ring flange securedtov the. stick, a rib-hinge-ringwith ribs arranged to butt against the said flange, said flange being adapted to restrict the opening movement of the ribs beyond a predetermined point, an inner ferrule with a slanting wall having a "cylindrical section imposed thereon and grooved,
